DETACHABLE SCROLL FOR PORTABLE DESKS.

Application filed February 11, 1920.

To all whom it may concern:

Be it known that I, LEWIS E. MYERS, citi- Zen of the United States, residing at Valparaiso, in the county of Porter and State of Indiana, have invented certain new and useful Improvements in Detachable Scrolls for Portable Desks, of which the following is a specification.

My invention relates to improvements in detachable scrolls for portable desks and it consists more especially of the features hereinafter pointed out in the annexed claims.

The purpose of this invention is to provide means whereby portable or other desks may be supplied with interchangeable topical scrolls, so as to increase their scope of educational and recreative usefulness; that makes provision for different positioned and variablesized display areas; that retains the use of a pivoted desk board in connection with the supporting frame, either in front or to the rear of the same; that provides means for display areas at an angle to the frame.

With these and other ends in view I illustrate in the accompanying drawing such instances of adaptation as will disclose the broad underlying features without limiting myself to the specific details shown.

Fig. 1 is a side elevation partly in section of a desk frame and accessories.

Fig. 2 is a plan view of one edge of the frame.

Fig. 3 is a detached plan of the frame, extended bale, etc.

Fig. i is a perspective view of a bale retaining spring plate.v

In carrying my invention into practice I employ two edge or side pieces 1. These are joined together by an upper cross-piece 2. lower one 3 and other intermediates 4i and 5. At the top on the rear side a handhole cross piece 6 is secured to the sides 1. These cross pieces determine the width of the frame. The rear side of the frame is enclosed by a cover or backing 10 which may have a map or other study subject mounted thereon. Between the cross pieces l and 5 variously arranged compartments may be placed as desired. The side pieces 1 may be made of greater relative length than shown in the drawing so as to provide a longer up-and-down display area in which case the side arms 16 of the supporting bale would be lengthened, accordingly.

Serial No. 3518405 In ordinary use desks of this type employ a swinging desk board 21 which may be a black board on one side and a drawing board on the other provided with side rails 22. The board 21 in its space between the rails is slightly wider than the width of the main frame which allows the board to be swung up against the front of the frame to close it as the side rails overlap the parts 1. While in this position the board is held by the bale 15 in position F with its short ends 17 in the openings 26 formed in the side rails 22 and spring plates 18 that enter grooves 23 of such rails. In its open or bale position G the board may engage front notch 34 or the rear notch 35 accordingly as the board is supported by the bale 15, in posit-ion G at the front of the frame or in position H at the rear of the frame. While so positioned it may be locked by a suitable bolt (not shown in detail) from the frame 1, which enters an opening in one of the side bars 22.

l/Vhen interchangeable topical scrolls 33 are to be used in connection with the frame it may be attached to a convenient place on the wall by means of ordinary screw hooks 14: which engage screw eyes 13 attached to the sides 1 of the frame, the board 21 is detached from the bale ends 17 and a transfer or storage roller 28 having end extensions 30 and holes 31 is placed on the bale 16 so that the bale ends 17 enter holes 31. The bale itself may be held horizontal by notches formed in. spring plates 18 as the straight portion 27 of the bale snubs into them, or it may be held in position G when also detached from the board 21 by notches in the spring projection 19. These plates are formed right and left hand. one for each upright '1. They also form a bearing for the bale '15. At the point where these spring plates are. located the uprights l are recessed under the spring portion of the plates so as to permit the sprlng ends to have in and out movesmaller diameters pass through holes in the uprights 1 (not shown). Heads 2 lare placed on these rollers to retain scrolls 33 in correct endwise relation as they are wound on the rollers. The transfer rollers 28 have knurled heads 29 to locate the endwise position of the scrolls and free ends 30 in which central holes 31 are formed for the bale ends 17. r

The free ends 30 facilitate the handling of the rollers 28, there being as many of these as there are separate subjects. On account of such ends the scrolls will not be so readily soiled, besides they serve to lengthen the transfer rollers to meet the bearing ends 17 of the bale. In addition they also serve to support the rollers in suitable filing cases.

The transfer or storage rollers may be filed in specially constructed cabinets provided with retaining means for each roller but as such filing accessories do not form a part of the present invention they are not shown.

It will be noted from the drawing that with the three relatively permanent rollers 7, .8 and 9 and .one transfer roller 28 with a scroll .33, numerous combinations, in position and extent of the display portion of the scrolls, may be secured. A transfer scroll .33 on its roller 28 is placed on the bale ends 17 with its rear end on the out side. This end is placed in slot 32 of roller 8 and this roller is turned to unwind the scroll from roller 28. This gives, with the bale in position E, a short inclined display portion B. .After the scroll has been wound onto roller 8 its front end will be on the outside.

In the ordinary position of the scroll with its contained data, on one or both sides it is run off from roller 8 onto roller 7 hich gives the display ar a A. Iiird r to make each scroll serve a double purpose it is printed on both sides, and for this reason the scrolls must be detachable as otherwise it will be impossible to use both sides. This relation will be readily understood by reference to the drawing in which a scroll is shown fully wound on roller 8 with one display face standing to the right hand side of 1. As the conten s of ol er 8 ar wound onto roller 7 ill the d ection of he arrow, or anti-clock wise, the last end of the scroll is then passed through the upper slot 11, and then across the back 10 o the lower slot 11 onto roller 9, where it is wound as needed. In this way the reverse side of the scroll is brought to view for study or otherwise. Should the scroll be vfirst wound onto roller 7 then its front end can be passed through upper and lower slots v11, formed in the/backing 10 and then onto the lower roller 9. In this relation the display area D will be of considerably larger extent than that contained in A admitting of comparative study of sequential data. If the scroll roller 28 and the bale arms 1.6 are in the position G and the scroll is wound onto the upper roller 7 a long diagonal. display area. G is produced which may be modified in angle and extent by using roller 8 instead of 7. lVhen scrolls are to be taken off and stored or filed they are so manipulated that the rear end of the scroll is found on the outside when the transfer roller is filled. Sub titles may be printed on this end to facilitate the filing and use of these unique educational aids.

lVithout going into a lengthy schedule of uses to which this educational device can be put it is .sufiicient to say that it'has almost unlimited possibilities of expansion, its flexibility lends itself to all kinds of adaptat ons, h y, m t ematics, mus c, chemistry, forestry, agriculture, electricity, mechanics P r i ectu e, p ysiology, domest c sci n as onomy, etc, maybe brought within the reach of the student for study and re a o The presentation of study subjects n this mann r pl c s n the hands o the chi d as Well as the gr n person an inst ument of s lf-h lp which n it practical application is universal in it adaptations.
